NASA's Opportunity Mars rover remains silent nearly a month after a dust storm cut off contact with the spacecraft. Regular listening sessions by NASA's Deep Space Network have yet to detect a signal from the rover, which went into a low-power "sleep" mode in early June as a dust storm blocked sunlight, depriving the rover of power. The dust storm has turned into a major global event, but there are signs the storm may have peaked and may soon subside.
